Abstract
A method for the hands-free access to a motor vehicle (V) is combined with a method for monitoring tire pressure. More particularly, wheel units (20, 21, 22, 23) belonging to the tire pressure recognition system detect the cessation of low frequency LF transmissions caused by the recognition of a badge B paired with the vehicle in order to trigger the measurement via the wheel units of the pressure and temperature values prevailing in each tire of the vehicle. These pressure and temperature measurements are sent to a central unit (14), which is mounted on the vehicle, so as to provide the driver with this information. The temperature and pressure measurements are transmitted to the central unit as soon as the measurements have been taken, irrespective of whether or not the driver has entered the vehicle.
